- Abstract
A revision of the classification of taxa in the Eucalyptus dalrympleana complex within E. series Viminales from New South Wales using population level genetic data is presented here. It remains unclear if the complex is a natural grouping to the exclusion of other related species, and hybridisation between members of the complex and E. mannifera, E. viminalis and E. elliptica is recorded. In line with observations from field surveys, the two taxa from the North Tablelands region, E. dalrympleana subsp. heptantha and E. rubida subsp. barbigerorum formed a single genetic lineage and the latter is therefore considered a synonym of the former, given this lineage is most closely related to E. dalrympleana subsp. dalrympleana. The threatened narrow-range endemic taxon E. canobolensis is shown to be nested within the more widespread E. rubida subsp. rubida, and therefore the original circumscription of this taxon as E. rubida subsp. canobolensis is supported.
